Microscopic Green's function approach for generalized Dirac Hamiltonians
Jeyson Támara-Isaza, Pablo Burset, William J. Herrera
The rising interest in Dirac materials, condensed matter systems where low-energy electronic excitations are described by the relativistic Dirac Hamiltonian, entails a need for mic…
Dynamics of a quantum polariton vortex: Low excitation scenario
J. P. Restrepo Cuartas, C. A. Flórez-Acosta, J. D. Rodríguez-Durán +3
Quantum vorticity in polariton systems has been traditionally investigated within the frame of many-body phenomena under the mean-field or coherent approaches. In the present work,…
Edge states, transport and topological properties of heterostructures in the SSH model
R. Pineda, W. J. Herrera
In this paper, we discuss the topological and transport properties of binary heterostructures of different topological materials. Using the Su-Schrieffer-Heeger model and the metho…
Subgap states in two dimensional spectroscopy of unconventional superconductors using graphene
Oscar E. Casas, Shirley Gómez Páez, Alfredo Levy Yeyati +2
The two-dimensional nature of graphene makes it an ideal platform to explore proximity-induced unconventional planar superconductivity and the possibility of topological supercondu…
Transport in Selectively Magnetically Doped Topological Insulator Wires
Sergio Acero, Luis Brey, William Herrera +1
We study the electronic and transport properties of a topological insulator nanowire including selective magnetic doping of its surfaces. We use a model which is appropriate to des…
Spectroscopy of non-local superconducting correlations in a double quantum dot
L. G. Herrmann, P. Burset, W. J. Herrera +5
We investigate non-linear transport in a double quantum dot connected to two normal electrodes and a central superconducting finger. By this means, we perform a transport spectrosc…
